The forklift pallet fork hydraulic energy recovery system comprises a lifting oil cylinder, and the lifting oil cylinder is connected with an oil supply part and an oil return part through a lifting electromagnetic valve; the oil supply part comprises an oil supply pipeline and an oil pump arranged on the oil supply pipeline; the oil return part comprises an oil return pipeline, the tail end of the oil return pipeline is communicated with an oil inlet of the oil pump, the oil return pipeline is connected with an energy storage part, the energy storage part comprises at least one energy accumulator, and the energy accumulator is communicated with the oil return pipeline through an energy accumulator valve. At least one energy accumulator used for recovering hydraulic energy of the lifting oil cylinder is added, so that the energy utilization efficiency of the forklift can be greatly improved, and the cost is saved; by improving a forklift hydraulic system and a control method, the energy waste of a forklift lifting system can be effectively improved, the overflow loss is reduced, the descending stability of a pallet fork can be greatly improved, the operation is safer, and meanwhile, the working efficiency can be remarkably improved.

    本发明公开了一种叉车货叉液压能量回收系统,包括起升油缸,所述起升油缸通过起升电磁阀连接有供油部、回油部;所述供油部包括供油管道以及设置于所述供油管道上的油泵;所述回油部包括回油管道,所述回油管道的末端与所述油泵的进油口连通,所述回油管道上连接有蓄能部,所述蓄能部包括至少一个蓄能器,所述蓄能器通过蓄能器阀与所述回油管道连通,本发明在原有常规叉车液压油路基础上,添加了至少一个用于回收起升油缸液压能的蓄能器,能够大大提高叉车能量利用效率,节约成本;对于叉车液压系统及控制方法的改善,能有效改善叉车举升系统能量浪费,减少溢流损失,且能大大改善货叉下降稳定性,使操作更安全,同时能显著提高工作效率。
